Rare 'Balloon Syndrome' Causes Hedgehog to Puff Up Like a Beach Ball

What do you do when find a puffed-up, beach-ball-size hedgehog? You take it to the vet to be deflated.
That's what happened to a wild hedgehog in Scotland — named Zepplin by his rescuers at the Scottish Society for the Prevention of Cruelty to Animals (Scottish SPCA) — who was suffering from a rare condition called "balloon syndrome."
Zepplin was spotted by the roadside on July 23 and the Scottish SPCA was called in, according to a statement from the society.

After surgery, Zepplin "deflated" back to down to his normal size. Here, he's given oxygen as he recovers.
